Improvement in pumps



UNITED, STATES PATENT iii-ica JOSEPH A. STANSBURY, OF BALDWINSVILLE, NEWYORK.

IMPROVEMENT IN PUMPS.

To all whom 'it may concern:

Be it known that I, J. A. STANSBURY, of Baldwinsville, in the county ofOnondaga and State of New York, have invented certain new and usefulImprovements in Direct-Acting Force-Pumps; and I do-hereby declare thatthe following is a full and exact description thereof, reference beinghad to the accompanying drawings, making part of this specification.

Figure l is a side elevation of my improved pump; Fig. 2, a centralvertical section; Fig. 3, a plan with the top of the case removed toshow the interior arrangement; Fig. 4, a diagram showing the arrangementof the abutment and the guide for turning the wings of the piston; Fig.5, a diagram, in perspective, of the guide and piston-wings; Fig. 6, aperspective view of a portion of the hub of the piston-wings and thelower iiange in which it works.

Like letters of reference indicate corresponding parts in all thefigures.

My improvement belongs to that class where the pump proper is placedbelow the surface of the water, and where the column is raised byrevolving wings acting directly upon the body of liquid admitted withinthe pump-case.

As represented in the drawings7 the case is made up of a body, A, and acover, B, which are suitably bolted or screwed together. The body of thecase is provided with an induction-port, a, and a water-passage, b. Withthe cover or top is connected an elevating-tube, C, extending to the topof the well.

The body and cover of the case are provided with rims c c inside, Fig.2, within which rests a hub, D, that receives motion by a shaft, E,extending to the top of the well, and operated by any suitable means.The hub has aflange, d, projecting out from between the rims, andcentrally through this flange and through the hub passes loosely ahorizontal shaft, j', to the ends of which are riveted or otherwisesuitably secured wings g g, which, when standing vertically, just iillthe cross area of the waterpassage b.

In order to allow the wings to t closely to the peripheries of the rimsc c the flange d is notched iiush with said rims, as shown at l1, h,Figs. l and 6. The wings are set at right augles relatively-that is,when one stands vertical the other is horizontal.

On the inside of the case, at a suitable position, is secured a guide,Gr, which may be At the end of the guide on which the wings first strikeis a projection or stop, k, and also a small spring, Z, for firstreceiving the eolienssion of the wings and turning them into the properposition for riding on the guide.

At the proper position next the inductionportis an abutment made up oftwo parts, m and a, the former stationary, but the latter jointed bymeans of an arm, o, and pivot p, so as to rise and fall over thestationary part. The jointed part is also provided with a cam-face, q,inclined upward and backward to allow the wings to pass edgewisebetween, as' will presently be explained.

The action of the pump thus arranged will be-easily understood. Thewings revolving in the direction of the arrows carry the water in frontand discharge it through the tube C. At the moment the lower edge ofeither wing strikes the spring Z and stop k it is turned from avert-ical to a horizontal position, and, striking iiatwise on the guideGr, is steadily held and carried around to the opposite end of the guidein the same position. The same action that turns'this wing into thehorizontal position also turns the opposite wing into the verticalposition, since both are attached to the same shaft j', and this turnsfreely in the hub D. Thus the win gs turn into the vertical positiondirectly after passing the induction-port, and carry the water bodilybefore them, and turn into the horizontal position just before reachingthe abutment 5 and this action is infallible unless the pump becomesderanged, for one wing cannot turn without the other.

In the act of passing the abutment it will be `perceived that the latteryields or opens for the purpose, and this action is produced by the edgeof the wings striking the inclined cam-face q. There is thus but littleescape,

' while there is no danger of breakage.

The spring Z serves to break the shock of the concussion of the wings,and also serves to commence the turningmotion of said Wings beforestriking an unyielding stop.

This pump is valuable for all ordinary uses, but especially so whenlarge poweris required or when liquid having much sediment is to-beraisedfor instance, in breweries.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. The combination of the right angled wings q g, attached to andturning with the same shaft, and the guide Gr, when said parts are usedin connection With a pump, substantially as herein specified.

shaft f, the hub D, provided with the angey d, substantially asdescribed.

5. -The arrangement, as a Whole, consisting of the Wings g g, guide G,abutment m n, hub D, and spring l.

In Witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
